What your AI chat can build with it on Hypamoon, how it connects, and the sources we checked." url: https://hypamoon.com/connect-to/moss --- 1. [Connect to](https://hypamoon.com/connect-to) 2. Moss ERP and accounting # Connect Moss to Hypamoon Yes, with one catch. Moss has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today. Open ## The check Three questions about the API of Moss, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://developers.getmoss.com/) **A key you create yourself**\ **Yes.** An admin generates an API key under Settings, Company Settings, API Keys and confirms it in the Moss mobile app. [developers.getmoss.com](https://developers.getmoss.com/) **Versions or a changelog**\ **Yes.** Version in the URL path (v1) and a numbered changelog. [developers.getmoss.com](https://developers.getmoss.com/changelog) **How it signs in**\ Key ID and secret key are exchanged for an OAuth 2.0 client credentials token that lasts one hour, with read or write scope. **Webhooks**\ **Not confirmed.** **Hosting**\ Cloud ## Your own spend overview on Moss, built around your suppliers and teams. - Card transactions, expenses, suppliers and bank accounts, from the scopes you allow. - AI that checks transactions and suggests the right supplier and category, with a person approving. - A screen for team leads and a weekly email for finance. ### Ask your chat Answers straight from your Moss data, in Claude or another chat with the full Hypamoon connection. - Which card transactions from last week are still missing a receipt? - Which suppliers had the biggest spend increase this quarter? ### On a schedule Moss has no webhooks we could confirm, so an agent checks every 15 minutes and decides what happens next. 1. Every 15 minutes New card transactions since the last check. AI decides AI matches each one to a known supplier and flags amounts that look unusual. Then Finance gets one email with what needs a look. ### A screen for your team or customers An app on your own address, with sign-in, on top of the same Moss data. - For your team Team leads see spend per supplier and per month for their own team. Moss stays the core: your chat builds the rest on its API, as an adapter plus an app and agents in your Hypamoon project. Reading starts after you click Allow in the portal. Every change an agent or a chat makes in Moss waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters) ### Good to know - Moss signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Moss takes more work: ask your chat to check this first. - Only admins can create API keys. Tokens expire after one hour, so the adapter requests a new one when needed. ## Try it in your chat Fill in what to read and write, and send it.
